Tihany Geophysical Observatory started its activity in the year 1955. Since that time the observatory has continuously recorded geomagnetic data.

Geomagnetic measurement requires anomaly free geological environment, special buildings (the buildings have to be free of ferromagnetic material i.e. iron) and careful operation of unique instruments. A further important task is to ensure the satisfied environment of the measurement e.g.: temperature stability, uninterruptible power, lightning-safe solutions etc. The data acquisition is also a cardinal question because this system guarantees the correct time stamps of the samples and this system ensures the required digital format and data security of the recorded data.
